TEHRAN: Tehran has deployed a recently delivered Russian-made long-range missile system to central Iran to protect its Fordo nuclear facility, state television said Sunday.
Protecting nuclear facilities is paramount "in all circumstances" General Farzad Esmaili, the commander of Iran's air defences, told the IRIB channel.

"Today, Iran's sky is one of the most secure in the region," he added.
A video showed an S-300 carrier truck in Fordo, raising its missile launchers toward the sky, next to other counter-strike weaponry.
The images were aired hours after supreme leader Ayatollah Ali Khamenei gave a speech to air force commanders, including Esmaili, in which he stressed that Iranian military power was for defensive purposes only.
"Continued opposition and hype on the S-300 or the Fordo site are examples of the viciousness of the enemy," Khamenei said.
"The S-300 system is a defence system not an assault one, but the Americans did their best for Iran not to get hold of it."
The Fordo site, built into a mountain near the city of Qom has stopped enriching uranium since the January implementation of a nuclear deal with world powers.

Under the historic accord, Iran dismantled most of its estimated 19,000 centrifuges -- giant spinning machines that enrich uranium, keeping only 5,000 active for research purposes.
Iran and the United States, Britain, China, France, Germany and Russia negotiated for more than two years before signing a historic July 2015 agreement that removed some international sanctions in return for curbs on Tehran's controversial atomic programme.
